<h2>Description</h2>
<p>The Average() method takes a set of images and averages them together.
Each image in the set must have the same width and height.  Average()
returns a single image with each corresponding pixel component of
each image averaged.   On failure, a NULL image is returned and
exception describes the reason for the failure.</p>
<p>The format of the AverageImage method is:</p>
<pre class="literal-block"><a class="reference external" href="../api/types.html#image">Image</a> *AverageImages( <a class="reference external" href="../api/types.html#image">Image</a> *image, <a class="reference external" href="../api/types.html#exceptioninfo">ExceptionInfo</a> *exception );</pre>
<p>A description of each parameter follows:</p>
<dl class="simple">
<dt>image:</dt>
<dd><p>The image sequence.</p>
</dd>
<dt>exception:</dt>
<dd><p>Return any errors or warnings in this structure.</p>
</dd>
